Spray Dryers
Attomo is the leading manufacturer and turnkey supplier of spray dryers and also deals with engineering consultation and designing.
Spray drying involves the use of spray dryers, which are devices that separate a liquid stream into a solid solute or suspension and a vapor solvent. The solid component is typically collected in a drum or cyclone, while the liquid input stream is transformed into small droplets by spraying it through a nozzle into a hot vapor stream. This nozzle is essential for maximizing heat transfer and the rate of water vaporization. The size of the droplets can vary from 20 m to 180 m depending on the specific nozzle used. Compared to alternative drying methods, spray dryers are known for their ability to rapidly dry a product.
Spray dryers are specifically designed with different atomization and flow patterns to accommodate the unique characteristics of the feed and product. They are capable of drying a wide range of products.
Spray Drying directly converts liquid feed solutions, emulsions, dispersions, or slurries into powder or granules, making it a one-step drying process. Read more about spray dryers and our services in relation to spray dryers below
Rotary Dryers
Rotary dryers are known for their strong and durable construction. The solids undergo a drying process as they are exposed to a hot stream of air while passing through the dryer.
Indirect Rotary Dryers
Indirect Rotary Dryers consist of a rotating shell with an inner concentric shell. Hot combustion products pass through the inner shell without touching the product. The product is dried through radiation and conduction.
Advantages
- Products which can get oxidised or flammable can be dried very easily.
- Continuous operation and versatile application
- Low operating & maintenance cost
Frequently asked question about Dryers
The best way to dry heat-sensitive or flammable products is to use an Indirect Rotary Dryer. At Attomo, these systems utilize a rotating shell with an inner concentric shell where hot combustion products never touch the material. This prevents oxidation and ensures safe, continuous operation through radiation and conduction rather than direct contact.
A Spray Dryer is the most efficient choice because it converts liquid feed solutions, emulsions, or slurries into powder or granules in a single step. Attomo’s designs utilize specialized nozzles to transform liquids into droplets (20m to 180m), maximizing heat transfer and ensuring rapid water vaporization for high-quality output.
Yes, Rotary Dryers are specifically engineered for high-durability and continuous industrial applications. These systems expose solids to a hot air stream as they pass through a robust rotating shell. Attomo’s rotary units are preferred in chemical and distillery plants due to their versatility, low operating costs, and minimal maintenance requirements.
The most critical technical component is the atomization nozzle, which determines the droplet size and rate of vaporization. Attomo, a leading turnkey supplier, customizes these nozzles and flow patterns to match the unique characteristics of your feed, ensuring the solid solute is effectively collected in a drum or cyclone.
